GRIP HOOK.

Application filed October 23, 1920.

To all whom it may concern:

Be it known that I, Lucius HANnY, a citizen of the United States, residing at \Voodlynn, in the county of Camden and State of New Jersey, have invented new and useful Improvements in Grip Hooks, of which the following is a specification.

This invention relates to grapples, and contemplates a construction wherein the relatively movable jaws are so connected that when the grapple is elevated the aws effectively grip the object being lifted in a manner to prevent said object from slipping from between the jaws.

The nature and advantages of the invention will be better understood when the folowing detail description is read in connection with the accompanying drawing, the invention residing in the combination, construction and arrangement of parts as claimed.

In the drawing forming part of this application like numerals of reference indicate the similar parts in the several views and wherein Figure 1 is a side elevation oi the device forming the subject matter of my invention.

Figure 2 is a view taken at right-angles to Figure .1.

Figure 3 is a view similar to Figure 1 showing the material gripping between the jaws of the grapple.

Figure at is a sectional view at the points of intersection of said jaws.

The device forming the subject matter of my invention essentially embodies the jaws l0 and 11. respectively which are disposed substantially in parallel relation, the shank 12 of the jaw 10 being slotted to slidably receive the shank 13 of the jaw 11. Manifestly, the jaw 11 is susceptible of movement toward and away from the j av' 10 and guided in its movements, while the shank 1 3 slides through the slot 1% of the shank 12. One wall of this slot is inclined as at 15 and against which one of the longitudinal edges of the shank 13 bears, while jonrnaled in the slot 1 to contact the opposite longitudinal edge oi the shank 13 is an anti-friction roller 16, A suspension link 17 is pivoted at a point in its length to the free end of the shank 12 as at 18, While one end of this link is pivotally con- Specification of Letters Patent.

nected-with the adjacent end of the shank 13, this connection being indicated at 19. The opposlte end of the link is provided with an opening 20 to permit the link to be connected to crane, hoist or the like in the usual well known manner. In Figure 2 I have shown an object 21 arranged between the jaws l0 and 11 of the grapple, and it is obvious that when the grapple and the object 21 are hoisted, the jaw 11 is forcibly held in corresponding relation with the jaw 11 whereby the object 21 is effectively held between said jaws in a manner to prevent slippage or falling away from the frame or the like.

\Vhile it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

lVhat I claim is 1. A grapple comprising a pair of relatively movable jaws each having a shank, the shank of one jaw being slotted to slidably receive the shank of the other jaw, a link pivoted at a point between its ends to the shank of the first mentioned jaw. and

a pivotal connection between the free end,

of the link and the adjacent end of the other shank whereby the second mentioned jaw is movable toward and away from the first jaw.

2. A grapple comprising a pair of relatively movable jaws, each having a shank, e shank of one jaw being slotted to slidably receive the shank of the other jaw, one wall of said slot being inclined, an antifriction roller journaled in said slot and contacting one side of the said sliding shank, and a link pivoted at point between its ends to the first mentioned shank, and a pivotal connection between the free end of said link and the adjacent end of the other shank whereby said second jaw is movable toward and away from the first mentioned.

In testimony whereof I affix my signature.
